CHAPTER

General Information

This chapter gives background information on the SOM-4450 CPU System On Module.

Sections include:

• Introduction

• Specifications

• Board Dimensions

1.1 Introduction

Advantech's SOM-ETX form factor System On Module provides a scalable solution that meets customers' advanced CPU and application development needs. The SOM-4450 incorporates a low power, fanless GX1-300 MHz processor that has become the embedded integrators' processor of choice. It uses a NS CS5530A chipset as its VGA/LCD controller, with single 18 bit LVDS interface and 64-bit graphics engine. The CS5530A display controller (LCD and CR T display support) allows sharp and clear LCD screen resolutions up to 1024 x 768 and CRT resolutions up to 1280 x 1024 @ 16 colors. Combined with the CS5530A system chipset is a RealT ek R TL 8139 ethernet chipset. It supports all functions of an AT-compatible industrial computer. There is one SODIMM socket that supports 16 MB to 128 MB synchronous DRAM. The small size (95 mm x 114 mm) and use of four high capacity connectors based on the proven ETX form factor, allow the SOM-ETX modules to be easily and securely mounted onto a customized solution board or our standard SOM-DB4400 development board.

Many gains were made by using the Geode™ GX1 processor. The GX1 processor provides the lowest power consumption combined with high speed 586 processing power. This GX1 processor also supports most popular web plug-ins and leverages existing software and hardware investments. Onboard features include an ethernet interface, socket for CompactFlash™ card , Enhanced IDE interface capable of Ultra DMA transfer protocol, one parallel port, two serial ports and a PS/2 keyboard/mouse interface.
